DEMOUNTABLE RIM.

To on whom it may concem;

Be it known that We EDGAR L. Gone and JACOB H. MnssINoEn, citizens of the United those wherein the rim is removable from same is to pro when viewed from the inside,

the stationary metal band on the folly of the wheel pro er; and, the-object of the uce an improved. means for attaching the rim to the metal band so. that it may be demounted bodily with its tire. This object is accomplished by the construc-' tion set forth in the following specification and claim, and shown in-the drawings wherein i i Figure 1 is an elevation of the wheel certain parts being broken away. Fig. 2 is a perspective detail of the fastening ring andhits fin. Fig. is a perspectivg, detail of the band, illustrating the beads with which its interior is provided.- Figs. 4 and 5 are enlarged cross sections through the rim and its flanges, taken respectively through one of its bolts and between two of said bolts. Fig. 6 is an. enlarged sectional detail of a portion of the fel-ly and its band. Fig. 7 is a planview' of the two ends of one of the flanges; and Fig. 8 is a similar view of the block intended to be inserted between them.

In the drawings the letter H designates the hub and S the spokes of an ordinary,

manner set forth below.

automobile wheel whose felly F is by pref-' erence made of wood surrounded with a 4-5 metal band M as shown in Fig. 6 and hav-' ing a valve-hole V. N o novelty is claimed for these parts, but the outer face of the band is shaped to coact with the rim so that the latter, carrying the tire, may be at tached to or removed from said band in the Coming nowimore particularly to the details of the'present invention, the radially outer face of the band M is formed flat or nearly so for about half of its width as shown at 1, a nd slightly flaring or conical Specification of Letters Patent. Application filed May 2, 1912. Serial No. 694,787.

' face for the reception of the tire which "notches are passed bolts 15 .V through which passes 'and the four which it separates and Patented NOV. 19, 1912.

for the other half of its width as shown at 2, and through the flaring portion and possibly extending slightly into the other portion are out four transverse grooves or notches 3 for a purpose to appear. mountable rim is made up of arather wide metal band 4 preferably flat on its outer may be held thereon by any suitable means, and having its inner face provided with beads which are shaped as best seen in Figs. 4 and One of these we call .the plain bead 6 and the other the beveled bead 7. The latter is intended to coact with the flaring portion 2 of the band-M, whereas the internal circumference of thelain bead is less than the external circum erence of the relatively flat portion 1 of said band, and between these parts maybe passedthe thinner portion or fin 8 of a ring whose flat body 9 is of a size to come up against the outer face of the plain bead 6 as seen in Fig. it The body are provided with openings 10 at proper points, and the'beveled bead? with notches 1. also at proper points to register with the notches 3 in th periphery of the band, and through the registering lqopenings for holding all parts ,tnget'her. The band in V and the inneredge of the fin a notch inner tube in a manner which will be clear. Whenthis demountable'rim is to be applied to a wheel, it is passed over theisame until the beveled inner face of the bead 7 contacts with the beveled outer face of the flaring portion 2 of the band M, care being taken to have the holes V and V in register notches 3 and 11 in register in a manner well understood by the autoist.

The de-' has a radial openthe valve of the and the fin of this ring Thering 9 is then applied, its fin '8 passing ,between" the flat portlon l and the inner edge of the plain bead 6, and here again the notch. V 1 come opposite the alined holes through which pro ects the valve of the tire. The four bolts are now inserted through the registering openings in the ring and notches in the other members, and

htened up, and as their nuts applied and ti ts the tapering or strain is put upon the b0 fin 8 is drawn forcibly bewedge-shaped tween the contiguous faces of the parts therefore caused to hold this side of the rim tight around the felly and metal band,

while simultaneously the beveled face of the .other bead and the flaring portion of the band are also drawn into forcible contact and the parts are braced at this side of the wheel. Hence it will be seen that the simple tightening up of four bolts reliably locks the rim upon the wheel so as to prevent its dislodgment in either direction and also to prevent it from creeping.

' While the tire may be held on the rim .by any suitable means, we preferably provide rim along each edge with an' inwardly -projecting rib 20 under which may be hooked the rib 23 along the inner edge 0f a flange 21 whose outer edge is inturned at 22 so as to engage the tire casing. There are by preference two such removable flanges, each formed in the shape of a ring split as seen at the point 24 in Fig. 7, and for distending each ring after it is put in place we preferably use an outer wedgeshaped block 27 and an inner and similar block 29, both pierced for the passage of a bolt 28 having a nut .31 at its inner "end. The undercut extremities of the outer block move on the ends .25 of the ring which are .beveled and preferably grooved as at to receive tongues 37 on said block to prevent, the latter from lateral dislocation. However it will be understood that any suitable employed and if the flanges are detachable I,

any suitable form of spreader may be employed for distending them when they are applied to the rim.

What is claimed as new is:

In a wheel having a demountable rim, the I combination with the felly, and a band around it whose periphery is fiat at one side and flaring at the other and provided with flat portion of the band, a fastening ring I having an axially projecting fin adapted to be passed between said plambead and the fiat portion of the band and pierced with openings registering with said-notches, and

bolts removably engaging theopenings and notches. P p

In testimony whereof we have: hereunto set our hands 1n presence of two subscribing witnesses.
